Alpine 7390

Little is documented about the Alpine 7390. What survives comes from a single period installation feature.

HiFI-Stereo (May 1989, p.85) described the 7390 as a cassette receiver and CD controller unit, installed in the dashboard of a 1988 BMW M3. It ran the system in that car. The system had two 15-inch Pyle subwoofers hidden in the back seat, a midrange and tweeter in a custom Z-Box enclosure in each front door, and a Mitsubishi Mesa 95 cellular phone. An A-400 amplifier ($665), strapped into mono, powered the subwoofers at up to 400 watts.

That is about all the period record offers. The 7390 appears to have been a short-lived or niche model - a combination cassette receiver with CD control capability that integrated into Alpine's component car-audio systems of the late 1980s. No specifications (power output, frequency response, dimensions) have been found. No production years, original standalone price, or factory literature have surfaced. The archive keeps the model as a reference point from one enthusiast installation.
